Question 4 point
Ronch [10]

Answer:

5393.4gH_2O

Explanation:

Hello there!

In this case, for the described chemical reaction, we can write:

CH_4+2O_2\rightarrow CO_2+2H_2O

Thus, by considering the 1:2 mole ratio of methane to water, and the molar mass of the latter (18.02 g/mol), the following is useful to calculate the mass of water that is produced:

149.65molCH_4*\frac{2molH_2O}{1molCH_4} *\frac{18.02gH_2O}{1molH_2O}

Which is equal to:

5393.4gH_2O

Which is not among the choices.

Regards!

What has the biggest impact on a region,weather or atmosphere.
andreev551 [17]

<em>Weather.</em>

<em>You see how the weather is in a certain place can determine how the plant life and just life in general would live. It can also effect people. Let's say there was a drought somewhere, this would effect people whereas, they could lose a significant source of water and food because it would make them likely have to find a new water source or the animals would. Weather also effects the land in harmful ways. For example when it floods, the ground gets muddy but can also get so muddy below a certain area, that the soil entirely collapses into the ground (that would be a sinkhole).</em>

<em>There are picture below to show you some of the effects.</em>
